Abstract: The effect of dexamethasone (5-80 microg/ml) on ovarian function and embryo development was studied in mice. The follicle bio-assay revealed no effects of DEX up to 40 microg/ml on folliculogenesis and oogenesis, whereas 80 microg/ml hampered follicle differentiation and oocyte maturation. Androgen, estrogen and progestin secretion patterns were strongly impaired at all doses levels. However, the ovulation-induced progesterone increase indicating that the steroid pathway was activated in presence of DEX. Applying the oil-free mouse embryo assay...
